all "whom it concern:

lie it known the: l, FRANK E. GUYOTT, e, e izen o t United States of America, re-

' orthempton, in the county of i a nil Stale of lilasssclmsetts, have invented new and useful Improvements in vlvos, of which the following is s specifiesl'lS invention relates to improvement in 01S 01 bibs, more particularly to de s of this elnn'ectei' wherein provision is e for enabling: the main valve to boreell for i'enewzil or repairs without the 't-v loi' sho ting oil the water or steam,

or shelling ell she supply in the main pipe.

fl'ilxli these and other objects in view, the inveilion consists in certain lestiires of eons'l notion hereinafter sl'ii nvn and described l spool-flesh: pointed out in the claim and in he Ll Kelvin-gs employed for illusii'sling the invention is shown the ni iprovecl "form oi embodiment of the some, and in the drawings '7 t nploye l:-ldigure 1 is longitudinal L'lC l section on the line l-l oi limlltom plan view e' 3 seciionsl view on the line 4 of Fig. l. l 4 is a sectional detail valve in open position fillll the auxiliary valve in closed position.

The inipi'ovea'l (levies comprises a shell or lioi v having main valve end an auxiliary valve 1 2 intern'iollielae its ends, and lLllIQz'MlBLl, as at e, at one end to receive e sleeve (E 11 pen a liooilfond. with n guide-Way n hot-Ween the main valve seat and the threaded end of the shell, and With on outlel 5 leading lroni the shel oenveen the valve seal 3 soil the guide-Way 12;, this portion of 1 she shell forming on outlet chamber,

shown. Sliclslaly disposed in the guide-Way nriier-pieee in one side of wiiicli a valve stem? 1S seemed, as at m the outer end of o lo vs stein being f: llllfill reel-angle loll" and jttnig into a rectangular socket g hood f, the valve stem being sein position by a screw '1' operating filirough ihe lioodf. The slicl a is internally l'ln'eeoed. within the hoodf, as at c, to receive s gland operating againstpaoliing lc-Jc, to prevent leakage around the valve stem. Sealed upon the nisin valve seat 8 is a. valve disk preferably of flexible material secured by a screw 9 to a eonneeting piece 0, the connecting piece having a flange at one end fitting into a COII'QSPOIHIllIIg cavity in the -piece w. By this mos-us the main having e disk valve is rotetively connected to the terrierpieee 92 and movable longitudinally of the shell therewith, liereina'llez' explained.

The screw r is provided. with a projecting stud q extendingbeyond the auxiliary seal; 2. lletsoliobly eonneciecl to the shell is an extension piece y forming the inlet to lhe valve shell and WliEll on internal i'elstivoly large chamber having spaced longitudinal guides w upon which an auxiliary valve device v is slidably disposed, the member '0 of flexible material u secured thereto by e screw 2f, the screw adapted to be engaged by the free end of the stud g, and thus maintained normally out of eonaec'n Wl'lll the auxiliary volve seal- The valve member is thus freeeo n'iove Within the chamber of the Xl ension piece 3 and permit the inilowing Water or steam to pass around it 0 Within the spaces beliveen the ribs w.

The main valve 32 is operated by rotating the hood as will be obvious the turnin of i 7 I the hood in direction opening the main valve and the iz'erinng of the hood in the the complete opposite iliieot-ion elosing one main valve through the eooelion ol' ilie stein ii, carrierpieoe o and connecting piece 0. A certain degree of flexibility is therefore assured be tween the stem ii, the earrienpiece n and the connecting piece 0, so that the valve is free to seat itself upon the seat 8. The main valve 2) may thus be moved to a snllicienl: extent to enable the WLlZQl or steam to flow freely from the inlet; of the casing past the auxiliary valve 12 and the main valve 22 and be discharged tli'rougli the pipe '0, and so long as the main valve g) operation will continue. 1*: is not necessary to draw the valve 39 to the position shown in Fig. *l in order to permit of a discharge through the outlet 5, out only partway over opposite sides of said ontle in Wliioh position of the valve 91, the stud g would engage the valve "0 and hold away from the seal; 2 thereby permitting of a proper discharge to the outlet 5. Should, however, the main valve require renewal or Y s-peeking, the serew i is removed, the hood j" unsei'ewed, and the stem 7i drown outward onirying with it the valve p and necessarily Withdrawing the stud g sndpermieting the pressnrein the rear of the auxiliary valve so close the letter upon the auxiliary seat 2 and thus shut off the out-flow. Upon the return of the valve 3) to its position Within the shell, the stud. Q will detach the auxiliary valve from reins-ins pei'fec u this the seat 2 by contact with the head of the screw t, and restore the valve to its former condition.

Having thus described the nature of the invention, what is claimed as new is A valve oi the class described comprising a shell having a. main valve seat and an auxiliai'y valve seat oppositely disposed intermediate the ends and an inlet at one end. and guhle-way near the other end and a dis eha vhainher between the guide-Way and main valve scat and an outlet leading from the discharge chamber an inlet chamber between the inlet and the auxiliary valve seat, terrier-piece slidzible in said guide-way and an operating stein projecting from one endol said ("Ii-Pier main valve adapteesase ed to be seated upon the main valve seat and a connecting piece rotatively uniting the main valve and the carrier-piece, a stud prejecting from the valve and extending in advance of the auxiliary valve seat, and a supplemental valve device loosely disposed in said inlet chamber and normally maintained out of engagement with the auxiliary valve i sent by said stud when the main valve is in closed 01' epen position, and vadapted to ensaid auxiliary valve seat when the main valve is to he removed from the shell.
